first off, never buy a "pro-painted" figure when the acution doesnt show a picture of the model. If you are a collecter, not a player, then always make sure that the colour scheme of the model for sale fits the colour scheme of your army(dont pick models with the main color of red for a green army). If the seller is truly proud of his painting then he will have many photos, and the price will most likely be high. Do not buy "pro-painted" models for under the retail price, this shows that the model is not pro-painted, the seller just put that to attract buyers. Then, look at the model itself. If the model does not fit your every want, dont buy it. Someone will auction off another that will be exactly what you're looking for. When examining the model, look at all cloaks/armor. These will be painted with utmost care. They will certainly have shading and highlighting on them. If not, the model is not truly pro-painted. Look at the weapons and belt next. A pro leaves no crevice unpainted to be certain that the details accommodate your needs. Then comes the base. Most pro-painted models will have the model in a converted stance, normally resting upon an enemy or a rock. A painter would not want to ruin his model with a poor basing job. Also, in the actual game there are limitations to the size of the base. Make sure that the base does not exceed this limit(20mm for the normal base, can be bigger for monstrous creatures). I hope this guide helps you the next time you wish to expand your warhammer army!
